legacy-type-mapping

What problem does it solve?

This Skill assists in managing the complex process of evolving persisted class structures, including renaming, retyping, and relocating classes and fields, without rewriting stored files.

Core Features & Use Cases

• Schema Migration Guidance: Provides instructions for renaming classes and fields, dropping classes, and applying explicit mappings through CSV files.
• Custom Legacy Handlers: Supports implementation of handlers for complex transformations, such as splitting fields or handling nested object restructuring.
• Use Case: Imagine you need to rename a class and change field types across a large codebase while preserving existing data integrity, this Skill guides you through minimal disruption migration steps and the use of CSV mappings or custom handlers.

Quick Start

Use the legacy-type-mapping skill to guide schema evolution, apply explicit CSV mappings, and implement custom handlers when necessary.
